Now Black Holes Can Be Reproduce in Laboratory

Black Holes have always fascinated scientist due to their mysterious properties, but there is much to be learned about them. These strange regions once thought to be absent of light before research found that actually these are the regions with such an extreme gravitational force that nothing, not even light can escape from their surface.

ccording to a latest invention Black Holes (imitation of Black Hole actually) can be reproduce in laboratory now!

Black Holes: What are

they?

Let’s understand it through the example of our own earth:

The mass of earth creates the gravity the pulls the things towards it. With enough power we can escape the earth’s gravitational force. This is how space vehicles leave the earth’s atmosphere.

Now if we squeeze the size of earth to that of a marble. This will increase the mass and gravitational force of earth to such extent that it would be impossible to bypass that force. Black holes are also regions with such a large mass and gravitational force that not even light can escape from them. Due to this it is not possible to view Black holes, but their presence can be realized only by the nearby activities.

Till now scientist have done extensive research about these strange regions in the universe. We know how they born, where they occur, and why they exists in different sizes, but there is much to know about them.

How to Know More about Black Holes?:

Dartmouth researchers have now proposed a new way to explore Black Holes. They plan to reproduce the black hole at a smaller scale in laboratory.  A paper has been published in this regard in Physical Review Letters, August 20 issue.

This method of creating tiny black holes of quantum size will help scientist to understand the insights of Black holes. Stephen Hawking, eminent space scientist had proposed that, Black Holes are not totally void of activity and they emit radiations in the form of photon. This radiation is known as Hawking Radiation or Bekenstein-Hawking radiation.

According to Paul Nation, a co-author of paper and Dartmouth graduate student,

“Hawking famously showed that black holes radiate energy according to a thermal spectrum. His calculations relied on assumptions about the physics of ultra-high energies and quantum gravity. Because we can’t yet take measurements from real black holes, we need a way to recreate this phenomenon in the lab in order to study it, to validate it.”

Scientist has shown that how a magnetic field-pulse microwave transmission line containing an array of superconducting quantum interference devices can reproduce physics analogous to a radiating black hole. This system can be controlled in laboratory and quantum mechanics properties. They can also manipulate the strength of applied magnetic field.

Past Attempts in this Field:

Creation of Black Holes in Laboratory has been proposed before by scientists. It has been proposed using supersonic fluid flows, ultracold bose-einstein condensates and nonlinear fiber optic cables. But the main problem in these schemes was weak Hawking radiation or masked radiation due to overheating of device. This latest scheme is much more efficient than previous proposed models.

advanced helicopter : Draganflyer X6

Draganflyer X6 is an advanced helicopter that can be operated remotely without any pilot. It is designed mainly to carry wireless video cameras and still cameras. The Draganflyer X6 helicopter can be operated very easily with its hand held controller.

The Draganflyer X6 helicopter is based on a unique 6-rotor design that has been under development since early 2006. It uses 11 sensors and thousands of lines of code to self-stabilize during flight which makes it easier to fly than any other helicopter in its class. The on-board software of Draganflyer X6 is developed after extensive testing and development. Draganflyer X6 helicopter is a revolution in the field of Unmanned Aerial Vehicle (UAV).

It can be used very efficiently for various applications and it is ideal for spying on the enemy in a safe and reliable manner.

MOVE OVER HYDROGEN, MAKE WAY FOR MAGNESIUM POWER

Magnesium burns as a white hot flame in fireworks.

•      Magnesium could work better than hydrogen in fuel cells.

•      There's enough magnesium in seawater to provide energy for 300,000 years.

 "When people talk about alternative energy, hydrogen often comes up. How about magnesium? We’ll see. Today, on Engineering Works! Listen to the podcast."

 

Magnesium is nifty stuff. Pure magnesium is a silvery metal, and you probably remember from high school chemistry that it burns with a hot white flame.

 

While a lot of research has already gone into using hydrogen to store energy, either directly as a fuel or as part of fuel cell systems, some researchers think we should be looking at magnesium as a way to store energy. Magnesium stores about 10 times as much energy as hydrogen. And there’s enough magnesium in seawater to provide energy for 300,000 years

 

Engineers at a Canadian company are working on a fuel cell that uses magnesium, air and water to produce electricity. An Israeli researcher has come up with a magnesium-based battery sort of like the rechargeable lithium-ion batteries we all know about. And a California researcher is working on a way to use magnesium to produce hydrogen for fuel.

All of this sounds good, but there’s a problem. It takes a lot of energy to purify magnesium to a form we can use. Maybe more than we’d get back. One researcher in Japan thinks he has the answer: solar energy to power a laser that would give us the almost 6,700° F. heat needed. We’ll see how that turns out.

Our magnesium power is somewhere in the future, so we’re done. See you next time.
